Overview

The Blue Sea Systems 8039 is an extended DC panel label set with 120 labels for identifying common circuits on boat electrical panels. Each label measures 1.438 x 0.438 in. and uses reinforced, weatherproof material, which suits the larger label format found on many DC distribution layouts.

It is used on Contura Waterproof Fuse Panels, ST Glass Fuse Blocks, and raised rocker and toggle circuit breaker panels. On board, clear panel labeling makes day-to-day use simpler and helps when tracing a fault, isolating a load, or handing the system over to a technician after a refit or service call.

Key features

• 120 DC labels for broad circuit coverage across larger panel layouts
• Reinforced, weatherproof material that stands up better in damp marine spaces
• 1.438 x 0.438 in. label size for large-format DC panel labeling
• Fits Contura Waterproof Fuse Panels
• Fits ST Glass Fuse Blocks
• Works with raised rocker and toggle circuit breaker panels

Compatibility and fit

This set is meant for large-format DC panel labeling rather than smaller square label styles. It is a practical match when replacing worn labels, finishing a new panel build, or updating circuit names after adding accessories such as pumps, lights, electronics, or charging equipment.

For boats with mixed DC distribution hardware, this label set helps keep naming consistent across fuse panels and breaker panels that use the supported formats. That matters when more than one person runs or services the vessel, especially on cruising boats, fishing boats, and workboats where panel changes tend to build up over time.

Installation and setup

Apply the labels after final circuit names are confirmed and the panel face is clean and dry. Taking a few minutes to match circuit names across the helm, cabin, and service areas can make troubleshooting faster later, especially when you need to shut down the right load quickly.
